Introduction/Objective. Despite frequent side effects such as hypotension, spinal anesthesia (SA) is still one of the best anesthetic methods for elective cesarean section (CS). Intermittent, oscillometric, non-invasive blood pressure monitoring (NIBP) frequently leads to the missed hypotensive episodes. Our goal was to compare continuous non-invasive arterial pressure (CNAP) monitoring with NIBP in the terms of efficiency to detect hypotension. Methods. In this study, we compared CNAP and NIBP monitoring for hypotension detection in 76 patients divided into two groups of 38 patients treated with ephedrine (E) or phenylephrine (P), during 3 min intervals, starting from SA, by the end of the surgery. Results. In group E, significantly lower mean systolic blood pressure (SBP) values with CNAP compared with NIBP (p = 0.008) was detected. CNAP detected 31 (81.6%) hypotensive patients in E group and significantly lower number 20 (52.6%) with NIBP (p = 0.001), while in P group CNAP detected 34 patients (89.5%) and NIBP, only 18 (47.3%), p = 0.001. CNAP detected significantly higher number of hypotensive intervals in E and P groups (p < 0.001). Umbilical vein pH was lower within hypotensive compared with normotensive patients in E and P groups, with CNAP and NIBP, respectively (p < 0.001, p = 0.027 in E, and p = 0.009, p < 0.001, in P group). Conclusion. CNAP is much more efficient in hypotension detection for CS during SA, which allows faster treatment of hypotension, thus improving fetal and maternal outcome.

Arterial Pressure Monitoring

The Finapres (Ohmeda, Madison, U.S.A.) is a non-invasive device which continuously measures the arterial blood pressure in a finger and produces a real-time display of the arterial pressure wave. It consists of a finger cuff with an infra-red transmission plethysmograph, a servo control box and a monitor unit. The device was compared with intra-arterial pressure monitoring in twenty patients during induction of anaesthesia for elective neurosurgical procedures. The differences between the two methods were considerable, ranging from −40 mmHg to +26 mmHg for mean pressure. While the Finapres has potential as a non-invasive continuous blood pressure monitor, the current model Finapres, as supplied, displays too great a variability for it to be used as an alternative to intra-arterial pressure monitoring.

Background: Spinal anaesthesia has side effects like hypotension and bradycardia, which may be induced by sympathetic blockade and Bezold-Jarisch reflex (mediated by peripheral serotonin receptor, 5-HT3 type). The objective of the study was to evaluate the effects of type 3 serotonin receptors blockade by intravenous granisetron  pre-treatment  in  spinal  induced hypotension in parturient undergoing elective caesarean section.Methods: Fifty six parturient with American Society of Anaesthesiologists Physical Status I and II undergoing elective caesarean section were assigned randomly to receive either Normal Saline (control) or Granisetron 1mg intravenously five minutes before spinal anaesthesia. Spinal anaesthesia was performed with 2.2 ml 0.5% hyperbaric bupivacaine solution and then heart rates, systolic blood pressure, diastolic blood pressure, mean arterial pressure were recorded every two and half minutes for ten minutes and then every five minutes for till end of surgery after. Hemodynamic parameters were compared with baseline in each group.Results: Change in mean, systolic and diastolic arterial pressure compared with baseline value were comparable in both the groups, but use of ephedrine as rescue vasopressor drug was significantly reduced in granisetron group. The episodes of hypotension, nausea/vomiting and shivering were comparable in both groups.Conclusions: Type 3 serotonin blockade by intravenous granisetron pre-treatment does not reduce spinal induced hypotension in parturient undergoing elective caesarean section; however there is reduction in need of rescue vasopressor.
